The angle at which the airfoil meets the relative airflow is called the angle of attack. As the angle of attack is increased, the changes in pressure over the upper and lower surfaces and the amount of downwash (i.e. air deflected downward) increase up to a point (the stalling angle). Beyond this angle, they decrease. 4, record 7, English, - angle%20of%20attack

L'angle auquel le profil aérodynamique rencontre l'écoulement d'air relatif s'appelle l'angle d'attaque. Quand on augmente l'angle d'attaque, les variations de pression (au-dessus et en dessous de l'aile), de même que la quantité d'air repoussé vers le bas augmentent et cela, jusqu'à un certain point (angle de décrochage). Au-delà de cet angle, elles diminuent. 3, record 7, French, - angle%20d%27attaque

Record number: 12, Textual support number: 1 CONT
The incidence angle is commonly used to describe the angular relationship between the radar beam and the ground, surface layer or a target. A change of the radar illumination angle often affects the radar backscattering behaviour of a surface or target. The incidence angle changes across the radar image swath; it increases from near range to far range. In the case of satellite radar imagery, the change of incidence angle for flat terrain across the imaging swath tends to be rather small, usually on the order of several degrees. In the case of an inclined surface (slope), the local incidence angle is defined as the angle between the incident radar beam and a line that is normal to that surface. The local incidence angle determining, in part, the brightness, or image tone, for each picture element (pixel) and slope facet, is a key element in the prominent rendition of terrain features in radar imagery. 3, record 12, English, - incidence%20angle

The actual law of refraction was discovered in the early 1600s by a Dutch mathematician and geodesist, Willebrord Snel van Royen. (Because his name in Latin is "Snellius", the law is often called "Snell's law" instead of "Snel's law". 6, record 15, English, - Snel%27s%20law
